OpenAI has just announced: “Starting today, all paying API customers have access to GPT-4. In March, we introduced the ChatGPT API, and earlier this month we released our first updates to the chat-based models. We envision a future where chat-based models can support any use case.
Today we’re announcing a deprecation plan for older models of the Completions API, and recommend that users adopt the Chat Completions API.
Based on the stability and readiness of these models for production-scale use, we are also making the GPT-3.5 Turbo, DALL·E and Whisper APIs generally available.
We are working on safely enabling fine-tuning for GPT-4 and GPT-3.5 Turbo and expect this feature to be available later this year.” Have a look at it!
